在服务器上部署一些服务

个人使用的是腾讯云的轻量服务器，系统镜像选择的是 Debian 11，搭建的服务有 博客 HUGO 、私有网盘 Nextcloud 以及 Git服务器 GitLab

目前使用的是 Debian GNU/Linux 11 (bullseye) 搭建服务器，当然用的是 fish 作为 shell

一下服务搭建时，域名统一使用 example.com，请根据自己的情况修改对应的配置，用到一些基础依赖请自行安装

• Nginx
• Git
• PHP
• PostgreSQL
• Redis

Nextcloud

Nextcloud 是 ownCloud 项目的一个分支，一个开源的私有云盘应用，官方提供了包括 桌面以及移动系统的客户端。

PostgreSQL

创建用户 nextcloud 和数据库 nextcloud_db

1 2 3

sudo useradd $nextcloud_db_user --create-home --shell /sbin/nologin sudo -u postgres -H psql -c "CREATE USER $nextcloud_db_user WITH PASSWORD '$nextcloud_db_passwd'" sudo -u postgres -H psql -c "CREATE DATABASE $nextcloud_db_name OWNER $nextcloud_db_user"

Nginxm

配置网站，修改 官方示例配置文件 并保存在 /etc/nginx/sites-available/nextcloud

1 2	ln -sf /etc/nginx/sites-available/nextcloud /etc/nginx/sites-enabled/ systemctl restart nginx

Nextcloud 安装

下载 你需要的版本并解压到目录中

1

sudo -E wget https://download.nextcloud.com/server/releases/nextcloud-"$nextcloud_version".tar.bz2
sudo mkdir -p $nextcloud_path
sudo tar -jxvf nextcloud-"$nextcloud_version".tar.bz2 -C $nextcloud_path
sudo chown -R www-data:www-data $nextcloud_path

准备工作完成后，进入网页，设置管理员帐号和数据库。

Nextcloud 开启邮件服务

配置邮箱服务器前需要先修改nextcloud的代码，如下

1

5

cd /path/to/nextcloud
sed -i \
    "s/\$streamContext = .*;/\$streamContext = stream_context_create(array('ssl'=>['verify_peer'=>false, 'verify_peer_name'=>false, 'allow_self_signed'=>true]));/" \
    3rdparty/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php
systemctl restart php7.4-fpm

登录管理员帐号进行邮箱服务器配置即可

Nextcloud 优化

优化最常见的手段是添加缓存，这里是在配置文件中添加 Redis (uds) 和 APCu 支持

1

'memcache.local' => '\OC\Memcache\APCu',
'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => [
  'host'     => '/var/run/redis/redis.sock',
  'port'     => 0,
  'dbindex'  => 0,
  'timeout'  => 2,
],

还有就是开启缩略图，比如最大只有 512x512 的缩略图，可以提高访问速度，但是访问可能体验极差，毕竟点开图片你就给我看这个

1
2
3
4

'enable_previews' => true,
'preview_max_x' => 512,
'preview_max_y' => 512,
'preview_max_scale_factor' => 1,

至于默认的 JPEG 质量是 90，有点高的话，你可以用以下命令调低 (比如到 60)

1

occ config:app:set preview jpeg_quality --value="60"

上传大文件的话，可以看看官方的相关文档

Nextcloud 插件

Nextcloud 不仅自带了很多功能，也提供了插件用于扩展功能，官方称作 Apps，以下个人推荐一些插件，欢迎补充

Announcement center

公告发布

Registration

File access control

文件访问控制，可以添加规则来控制管理用户对文件的操作，参见 工作流

Music

音乐播放器

Full text search

全文搜索

GitLab

GitLab 是开源的基于git的 web DevOps生命周期工具，提供了Git仓库、问题追踪和CI/CD等功能。分为社区版和企业版，使用相同内核，部分功能社区版没有提供。 Gitlab 相较消耗资源，官方推荐的最低要求为 4C4G 可以最多支持500用户， 8C8G 最多支持1000用户，具体的使用受到用户的活跃程度、CI/CD、修改大小等因素影响。

由于暂时不需要，没有安装 Gitlab Pages，Gitlab的安装依赖 git 用户，以下是目录结构

Gitlab 依赖

目前Gitlab最新版本为 v14.8 ，下列表是部分依赖，细明详见 安装最低要求

另外需要注意，GitLab 支持的 pgsql 扩展主要有三个，在不同版本有所支持

• pg_trgm 最低要求 GitLab 版本为 8.6
• plpgsql 最低要求 GitLab 版本为 11.7
• btree_gist 最低要求 GitLab 版本为 13.1

安装相关依赖，建立数据库，将 Redis 设置为 Unix Domain Socket (UDS) 连接

• 定义变量

  检查 btree_gist 扩展是否启用

  1 2 3 4

  SELECT true AS enabled FROM pg_available_extensions WHERE name = 'btree_gist' AND installed_version IS NOT NULL;

• 安装并配置 Redis

  1 2 3 4 5 6 7 8 9 10 11 12 13

  如果主机上还有 PostgreSQL 以及 Redis，可以在 gitlab-*.service 文件 Unit 单元的 Wants 与 After 两个字段追加下面两个服务

  1 2 3

  [Unit] Wants=redis-server.service postgresql.service After=redis-server.service postgresql.service

• 启动相关项目

  1 2 3 4

  # start gitaly sudo systemctl start gitlab-gitaly.service # init database and activate advanced features sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production force=yes

• 检测应用状态

  1	sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

• 编译前端文件

  1 2 3 4 5 6 7 8 9 10 11

  # GetText PO files sudo -u git -H bundle exec rake gettext:compile RAILS_ENV=production # Assets sudo -u git -H yarn install --production --pure-lockfile sudo -u git -H bundle exec rake gitlab:assets:compile \ RAILS_ENV=production NODE_ENV=production \ NODE_OPTIONS="--max_old_space_size=8192" if test 0 -ne $status echo "\033[31m compile assets error. desc '--max_old_space_size' \033[0m" exit 64 end

• 设置 Nginx

  1 2 3 4 5 6 7 8

  sudo cp lib/support/nginx/gitlab-ssl /etc/nginx/sites-available/gitlab sudo ln -sf /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab sudo editor /etc/nginx/sites-available/gitlab sudo nginx -t if test 0 -ne $status echo "nginx config error. editor /etc/nginx/sites-available/gitlab" exit 64 end

• 二次检查程序状态

  1 2	sudo systemctl restart nginx.service gitlab.target sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

Gitlab基本配置完成，登录网站设置默认管理员密码即可登录，默认管理员帐号为 root

GitLab CI/CD

接下来安装 Gitlab Runner 最新版，使 CI/CD 可用

1
2
3

cd /tmp
curl -L "https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh" | sudo bash
sudo -E apt install docker docker-compose gitlab-runner

Gitlab Runner 提供了几种模式，分别是

• shell
• docker
• docker-ssh
• ssh
• parallels
• virtualbox
• docker+machine
• docker-ssh+machine
• kubernetes

virtualbox、parallels、docker-ssh 都是使用 SSH 的方式连接到镜像。而通常采用 docker 执行器就可以轻量化的实现各种环境的构建；如果你需要执行 CI 任务时多时少则可以选用 docker+machine；shell 就很暴力了，直接在主机上执行，但是需要自行搭建环境，这不如 container 来的灵活自在。

在管理员面板的 Overview > Runners 中获取到注册 runner 要用的 token。注册 docker 执行器的 runner

1

sudo gitlab-runner register --executor docker --docker-image alpine:latest

或许以后会改为 k8s 搭建 runner。先将 docker build 映射到 /tmp，只需要修改配置文件中的 volumes 为

1

volumes = ["/cache", "/tmp:/builds:rw"]

如果对 GitLab Runner 的配置感兴趣，可以参考官方文档。

sed -ie "s/email_reply_to:.*/email_reply_to: ${gitlab_email_reply}" config/gitlab.yml
cp config/initializers/smtp_settings.rb.sample config/initializers/smtp_settings.rb

将email启用后，还需要配置smtp，可以参考 官方教程，修改配置文件 config/initializers/smtp_settings.rb，将 ActionMailer::Base.smtp_settings 修改为以下内容

enable: true,
address: "mail.example.com",
port: 465,
user_name: "noreply@example.com",
password: "YourPassword",
domain: "mail.example.com",
authentication: :login,
enable_starttls_auto: true,
tls: true,
openssl_verify_mode: 'none'

开启对邮件的 S/MIME 签名服务，将你的S/MIME私钥保存到 $gitlab_path/.gitlab_smime_key，公钥保存到 $gitlab_path/.gitlab_smime_cert

1

sed -i "103s/# enabled:.*/enabled: true/" config/gitlab.yml

配置完成后重启服务即可，如果需要验证SMTP是否工作，可以使用以下命令

echo "Notify.test_email('$gitlab_email_reply', 'Message Subject', 'Message Body').deliver_now" | \
sudo -u git -H bundle exec rails console -e production

Lychee

Lychee 现在是由 LycheeOrg 维护的开源项目，旨在实现一个简单易用的照片管理系统，我们搭建服务将使用 4.x 版本作为示例

Lychee 是目前为数不多的支持 PostgreSQL 的图床

set lychee_path /path/to/lychee
set lychee_version v4.0.8
set lychee_host example.com
set lychee_db_user lychee
set lychee_db_passwd YourPassword
set lychee_db_name lychee

Lychee 依赖

由于 Lychee 同样也是 PHP 开发的服务，所以已经安装 Nextcloud 的情况下，并不需要再安装 PHP 相关的其他 package (当然除了 PHP 的依赖管理器 composer)

PHP >= 7.4，依赖的扩展 (可以使用命令 php -m 查看已安装的扩展)

• BCMath
• Ctype
• Exif
• Ffmpeg (optional — to generate video thumbnails)
• Fileinfo
• GD
• Imagick (optional — to generate better thumbnails)
• JSON
• Mbstring
• OpenSSL
• PDO
• Tokenizer
• XML
• ZIP

Lychee 安装

我们先创建数据库用户，Lychee 支持 MySQL (> 5.7.8) / MariaDB (> 10.2) / PostgreSQL (> 9.2)，我们继续使用 PostgreSQL 就好

sudo useradd $lychee_db_user --create-home --shell /sbin/nologin
sudo -u postgres -H psql -c "CREATE USER $lychee_db_user WITH PASSWORD '$lychee_db_passwd'"
sudo -u postgres -H psql -c "CREATE DATABASE $lychee_db_name OWNER $lychee_db_user"

我们将安装 v4.0.8，更多详细版本信息请浏览 更新日志

git clone https://www.github.com/LycheeOrg/Lychee -b $lychee_version $lychee_path
cd $lychee_path
composer install --no-dev
chown -R www-data:www-data $lychee_path

关于 Web 服务器的配置官方已经给出了 Nginx 和 Apache 的相关配置

最后只需要配置 Nginx 相关内容即可
